Global maps can present your posts in many ways
They can show just one category, custom taxonomy term, or custom post type, for example
Clicking on a post marker shows a customizable summary of the post or page in an info window

A Geo Search widget enables searching for content by distance from a search location

Marker clustering for Google maps

Location can be saved for all post types (including pages) users, and comments

Synchronize Geodata with the Geo location mobile client and other plugins

Comparison to Other Mapping Plugins

Geo Mashup was one of the earliest WordPress mapping plugins, first released
in 2005. Eventually the author began using it for freelance jobs, which he
still does. As such Geo Mashup is more tailored to customization and hacking than ease of
use, but many user-requested features have beenreleased
over the years. Geo Mashup creates three tables to optimize location
searches.

It’s just crazy how many mapping plugins have sprung up since then. If all
those developers had worked together we’d have just a few much better plugins.
I’ve been guilty of not reaching out to other authors. If you are a developer
interested in working together for a better WordPress mapping future, contact
me via my site and I’ll work with you.

Support

The author monitors WP Questions,
and there is a public Google Group.
The author doesn’t promise free support, but is amenable to questions that contribute something
to the community.

Beta Features

There are often two versions of the plugin available, stable and beta. The beta
version includes all the stable version features, and also new features that
need further testing. See the currentBeta Documentation
for more.
